Anchorage-independent cell growth is an important physiological process for cancer development. To assess the tumorigenicity, the unique property of tumor cells to grow in soft agar was considered as an in vitro test in immunosuppressed animals [6]. During anoikis cells are detached from the ECM by mechanical forces or some other means to undergo apoptosis by extrinsic and intrinsic pathways. Failure to undergo anchorage-independent cell growth can be as an important hallmark of cancer owing to its property of invading through blood vessels and lymphatic stream. In order to support this fact, there are evidences that the passage of non-oncogenesis monkey kidney epithelial cells in suspension culture formed an anoikis-resistant line which leads to the generation of hypodermic tumors in nude mice [7]. Moreover, melanoma cell suspension culture exhibited anoikis resistance and metastasis, when administered through tail veins of mice [8]. While these earlier findings are supportive of our hypothesis, the correlation of in vitro anoikis resistance and metastasis potential has not been yet confirmed in an orthotropic in vivo tumor model. Literature suggested the involvement of TrkB protein in regulation of metastasis by screening of anoikis. In this current study, suitable experimental design and tumor model were developed to prove our hypothesis.

Effect of S100A7 expression on Soft agar colony formation and tumorigenicity of head and neck cancer cells. a Anchorage independent growth of TU167 cells stably transfected with different level of S100A7 expression i.e. C1 and C2 clones along with vector-transfected. Results were representative photographs of soft agar colonies (n = 3). b Survival curve of nude mice orthotopically implanted with vector (pcDNA3.1) or S100A7 clones (C1 and C2) tumors. Nude mice were orthotopically implanted in the tongue with 1 106 Vector or C1 or C2 S100A7 stable cells and observation showed weight loss with time. Animals losing more than 25% of their initial body weight were sacrificed. All the vector injected animals survived greater than 25 days without significant weight loss and therefore were sacrificed at that time point. c IHC of S100A7expression in FFPE tumor specimens from vector, C1, C2 orthotopically injected nude mice.

One of the concerns about the brown trout is they aren't just outcompeting native fish, they are eating everything in the creek, from the small native fish like speckled dace to those aquatic insects which start their lives underwater but become flying insects like caddis flies and mayflies. They are the base of the food chain for a lot of birds. One of the neat things that I've observed in my time down by Bright Angel Creek is over the past couple years, I'll never forget the first time I saw a great blue heron going through the creek and catching those little speckled dace minnows. The amazing thing is you likely would not have seen a heron there five years ago because the trout had eaten out their traditional food source.

Yeah, the big trout are the ones we're after because we're going in during spawning season and so we want to get the big ones that are carrying the most the eggs, you know, and the ones that are going to produce a lot of offspring. And so if we catch a big trout, that's that's a big deal that we're cutting out possibly hundreds of offspring that could be, you know, raised in the creek the following year. But also getting little ones is just as important.
